-----------------------------------------------------------

You can currently use remote jcache in two ways:
1) with the caches preconfigured on the server (including clustered caches)
2) with the caches created through the JCache API but these caches will be local caches and will be created only on the node to which the remote cache is configured to connect (you shouldn't usually use this mode, it's available so that TCK tests can be executed without preconfiguring the caches on the server side but other that that you should use #1).

For #1 don't add org.wildfly:wildfly-controller as a dependency to your project and JCache will not attempt to create the cache on the server (you still need to use cm.createCache() otherwise cm.getCache() will return null).

> Furthermore, when using multiple nodes in the cluster and the cache is not amongst configured caches, it is created as 'local' only on one node (this relates to fact org.infinispan.jcache.remote.ServerManager is configured to use one specific management interface - which is btw hardcoded and cannot be changed). Exception can occur when trying to write into cache.
